Recommended Use: Best suited to street-performance builds and lightly to moderately modified cars where intake response and serviceability matter.
Technical & Fitment Notes
- Verify compatibility with the vehicle's existing intake, charge piping, engine management, and other forced-induction hardware.
- Power results depend on the complete combination and calibration; no specific power gain should be assumed from the component alone.
- Original catalog note: Note: NOT CARB Legal - This product is not currently CARB exempt and is not available for purchase in California & CARB States or for use on any vehicle registered with the California Department of Motor Vehicles. Features: - Kit includes Super Power Flow and Aluminum Suction pipe. Polished aluminum pipe improves engine room appearance. - Enjoy a distinctive induction sound. - Improving an air intake efficiency, HKS changed from flexible stock rubber hose to aluminum pipe. This significantly reduces an airflow restriction at an HKS flow bench test compared to the stock intake system. - Removable air duct (air guide) which has a wide opening is newly designed. This can be directly used on stock ECU even for the normal vehicle or the vehicle with a custom muffler. You can reduce more air intake resistance, removing the air guide. (*) - (*) ECU setting is required when combination use o
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
